The slope of the data will be equal to 2 for the book reading.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise to the run of the line.
Given that Jenny started reading her book for English class at 8:03 p.m. and she started on page 24. At 8:29 p.m., Jenny stopped reading and was on page 37.
The slope of the data will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 29 - 3) / ( 37 - 24)
Slope = 2
Therefore, the slope of the data will be equal to 2 for the book reading.

The vertex form of the equation of a parabola is y = (x + 7)2 + 13. What is the standard form of the equation? O A. y = 7x2 + 14x+ 62 O B. y = x2 + 43x + 32 O c. y = x2 + 7x + 13 O D. y= x2 + 14x + 62
Answer:
y = x^2 + 14x + 62
Step-by-step explanation:
y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.
Note: Use " ^ " to denote exponentiation.
Expand y = (x + 7)^2, holding the constant term to be added on later:
y = x^2 + 14x + 49 + 13
Combining the constants, we get:
y = x^2 + 14x + 62 (which matches Answer D).
After driving for 2 hours, Juan is 110 miles from his home. After driving 5 hours, he is 275 miles from his home. What is his average rate of change?
Answer:
392
Step-by-step explanation:
The average rate of change will be "55 m/h".
According to the question,
→ After 2 hours (t₁),
Juan is 110 miles (d₁) from his home.
→ After 5 hours (t₂),
Juan is 275 miles (d₂) from his home.
→ The average rate of change will be:
= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]
By substituting the values, we get
= [tex]\frac{110+275}{2+5}[/tex]
= [tex]\frac{385}{7}[/tex]
= [tex]55 \ m/h[/tex]

The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City A, what is the population density of City B?
Answer:
[tex]1600\ \text{people per square mile}[/tex]
Step-by-step explanation:
Number of people per square mile in City A is 6000.
In terms of size City B is a dilation of City A with scale factor 1.5.
This means a length of 1 mile in city A would be 1.5 miles in city B.
So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]
City B has [tex]\dfrac{3}{5}[/tex] of the population of City A.
So the population density of City B would be
[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]
The population density of City B is [tex]1600\ \text{people per square mile}[/tex].

Answer:
15xy-6x+5y-2
15xy+5y-6x-2
5y(3x+1) -2(3x+1)
(we pick one out of the (3x+1) brackets.
your final answer becomes:
(5y-2)(3x+1)
Answer:
(5y - 2)(3x + 1)
Step-by-step explanation:
Let's focus on those first two terms, 15xy and 6x. They have two factors in common, an x and a 3, giving them a greatest common factor of 3x. If we factor that out, the expression 15xy - 6x becomes 3x(5y - 2). Substituting that into our original expression, we get the new expression
[tex]3x(5y-2)+5y-2[/tex]
Let's group those last two terms to make our next step clearer:
[tex]3x(5y-2)+(5y-2)[/tex]
Now, each term has the factor (5y - 2) in common. We can pull it out to get the fully factored expression
[tex](5y-2)(3x+1)[/tex]

The bank contains pennies, nickels, dimes, and quarters. There are 4 more nickels than pennies. How much money does the bank contain
Of the 50 coins 10% are pennies and 42% are dimes
The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.
First, let's find the number of pennies in the bank.
Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :
10/100 × 50 = 5
Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :
42/100 × 50 = 21
Since there are 4 more nickels than pennies, the number of nickels is :
5 + 4 = 9
Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15
Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880

Find the sum of all multiples of 7 lying between
500 & 900
Answer:
Sₙ = 57/2 * (504 + 896) = 39900
Step-by-step explanation:
first multiple of 7 after 500 is: 72 *7 = 504
last multiple of 7 before 900 is: 128 *7 = 896
a₁ = 504
aₙ = 896
where n = 128-72 +1 = 57
sum of arithmetic sequence: Sₙ = n/2 * (a₁ + aₙ)
Sₙ = 57/2 * (504 + 896) = 39900
